I all whom it may concern:

,, nn'r'rA, citizen of theUnited States, residing H :a-t'Byesville, :in the county of Guernsey and I v State of Ohio, have invented-certain new and useful Improvements in Mine-Car Stops, of

, which the followingisaspecification.

-. This invention-is'a-mine-car stopandcagapparatus, and has for its object to provide automatic means for loading cars one by one onto the {cage by which they are carried tovthej mouth of the shaft;

The object of the invention is to provide an filIIlPI'OVBCl form of trip for releasing the stop,

, andfor allowing the stop to become-reset so as, to allowthe car to run onto thevcage,

' when the cage is lifted, so .as-to stop a subsequent car..g,The device ,alsoucomprises means to stop a second car and to hold the first stop and so on indefinitelyql;

The invention is illustrated i panying drawings, in W'hlOh J v Figure 1 is a side elevation ratus; and Fig. 2 is a plan view,

Referring specifical y to the drawlngs, 6 indicates the elevator or cage and 7 the cars which travel down the rails 8, the track being inclined slightly toward the shaft so that the cars will follow down by gravity. Located in position to be struck by the cage when it reaches the level is a bell crank lever or tripper A which is pivoted to brackets B secured to a sill b.

' I D are triggers, set back from the shaft, un-

der the track, and connected to the lever A by a forked rod- C. The triggers D swing on a heavy shaft E which is mounted in supporting bearings in a pair of depending heav plates or hangers J which are bolted to bars he triggersare normally raised by counterweights F, and the triggers'are connected together by a long bolt f. The hooks of, the triggers are ada ted to engage the lower end of the bumping lock Gwhich is quite heavy and is preferably faced with metal, and

swings on a heavy shaft H which is mounted 4 in bearings in two side bars I. These side bars rest upon a cross beam T at the front end, and at the rear end they work through heavy boxings 0 set on a tie U, and they are rovideol with springs P-which serve to cush- 1011 the stop by allowing the bars to yield to a certain extent when a car strikes the stop.

wrecking. Theuppei 1, Be it known that! I, CHARLES 2M. "HEN;

st-ruck by the burner of foient', but in 'ord'er tos on eaclr side of the bumpers or couplers same' until the first ,car is-Televated, after whichthe' second' car will followdown to the:

n the accomfnormally swing to vertical'p'ositidiif" of the appaweig and certain in operation and will effectively the scope of the invention.

vi {VA projects above the track A single. stop-wi li y sequent cars, I provide afhrtdpoiii'tirifg of two'bumping blocks N which swing iiil o'n a heavy cross shaft Vfmdiint ir'iltheib arings I. Two bumping blocks"ar' use i sated a sufiicient' distance apartf't fo cdn ip ilp cars, and between then ds 'o'ff "lever eing used to change the direicfiio -of 'iriotion d" herej; 1 10- above their centers of gravity, set-ha hey In operation, when a cage drops onto the lever A, said lever turns and by means of the rod 0 releases the triggers D, as shown in. dotted lines in Fig. 1, and this permitsthe bum ing block G to swing down when the lit of the loaded car comes against it, permitting the car to run onto the. cage. After the car passes the bumping block G,-. said block swin s to vertical position, and when the cage ifts, the triggers turn-back and catch the lower edge of the block, ready to hold the next car. This movement of the tri ers is roduoed by the counter-weights F; r hen t e triggers D are in the released position, as shown in dotted lines, the tri gers 'L, by means 0f the intermediate re s and lever, are raised to engage the lower edge said. blocks in position to stop the secon car. When the cage rises the triggers L are dropped or released, allowing the bumping blocks N to swing and permitting the car to pass down to the fore or main stop G.

The apparatus is "simple .in construction do the work indicated As intimated above, the, stop for'the secon'd car may be omitted if desired.

. Various modifications may be made within '1 claim;

1. .A car stop comprising a support located I .ofthe bumping blocks N, thereby 110mm" l the rails of the track, a stop block pivoted between said hers and normally hanging upright p'os'ltlon to stop a'car and adapted to swing down to pass a car, a trigger engaging the block and holding the same in por tion to stop a. car, and means to reieaso the trigger..

5.A car stop comprising a pair of bars slidably mounted between the rails of the track and extending lengthwise with re spect thereto and having depending hangers, a swinging stop block pivotally niounter'r on said bars, a trigger mounted in said hangers and engagingsaid stop block, means to release said trigger to allow the stop block to swing and pass a car and springs connected to the hers and acting to cushion the move ment thereof incident to contact oi a'ear with the stop.

4. The combination with a. cage in a shaft and a. track leading thereto, a swinging stop block supported between the rails of the track,anu arranged to swing up or down to stop or pass a car, a trigger pivotally mounted QCQQY sumac under the track and arranged to catch and hold the stop block in uprlght position, and

tripper in the shaft and arranged o be struck by the cage and connected to the trigger to release thesaine-when so struck,

5. A car stop comprising tore and rear stop blocks nivotally mounted to swing up.

extending lengthwise between the rails of the tracK and yieldingly supported, fore and rear stop blocks pivotally mounted upon said bais, to swing to upright or inclined position, triggers plvotaily mounted on the bars and engaging said-blocks to hold the same in Upilglli) position, connections between the triggers, whereby one is released when the ot': aris engaged, and means to operate the triggers.

in testimony whereof I afiix my signature in presence or two witnesses.
